Sybex CSG 11 - error - Appendix - p. 1175

[Alejandro Vizcaino]

Question #6 says that option 'A' is correct:

A. Calling clone() on any object will compile.


This is wrong because clone() has protected access in Object,
and calling clone() on any object will not compile, unless the object has overridden the method.

I forgot about that. Added to errata. Luckily, it's not an error in the Java 17 book because the entire topic was removed from the objectives

[Alejandro Vizcaino]

That's too bad because I actually enjoyed that chapter a lot... so much so that I bought the book you recommended Iron-Clad Java

[Jeanne Boyarsky]

I few (very few) pieces moved elsewhere. Most of the material is out of scope for the Java 17 cert. I'm not sad though. A lot of the stuff it covered for security wasn't useful in practice. It's tough because most of the interesting security material involves third party libraries or server side Java.

Iron-Clad Java remains a great book.
